  • Publication number: 20230408259
    Abstract: A disturbance estimation apparatus including a navigation data receiver, a thrust data receiver, and processing circuitry is provided. The navigation data receiver acquires navigation data including an actual position and time of the ship on a water surface. The thrust data receiver receives thrust data indicating a magnitude and a direction of a thrust force of the ship. The processing circuitry estimates a predicted position of the ship under an absence of a disturbance condition at a predetermined time in the future using a first state estimation model based on the navigation data and the thrust data and determines disturbance data including a drift direction of the ship drifted by an external force based on a difference between the predicted position estimated by the first state estimation model and an actual position of the ship at the predetermined time.

  • Publication number: 20230303232
    Abstract: To control an automatic steering appropriately regardless of a ship speed. An automatic steering device includes processing circuitry. The processing circuitry acquires motion information including a ship length and a ship speed. The processing circuitry identifies a non-dimensionalizing motion parameter based on the ship length and the motion information. The processing circuitry generates a dimensionalizing motion parameter by dimensionalizing the non-dimensionalizing motion parameter based on the ship speed. The processing circuitry sets a control parameter of the model-based controller based on the dimensionalizing motion parameter.

    Abstract: An automatic steering device includes an acquirer, and processing circuitry. The acquirer acquires a traveling state including a heading or a position of a ship, and ship information on the ship. The processing circuitry calculates a first evaluation value that is an evaluation value indicative of a performance for maintaining the heading of the ship or a route based on the traveling state. The processing circuitry calculates a second evaluation value that is an evaluation value related to a ship handling control based on the ship information. The processing circuitry sets a control parameter related to a motion control of the ship based on the first evaluation value or the second evaluation value.

  • Patent number: 6022204
    Abstract: A vane compressor has at least one of a front-side member and a rear-side member thereof formed with a suction chamber opening toward a cam ring, which has a substantially arcuate or annular shape and extends around a drive shaft. The cam ring has one end face formed with a refrigerant inlet port for supplying a low-pressure refrigerant into compression chambers formed between vanes. Alternatively, a front head is arranged on one end face of the cam ring. A shell encloses another end and an outer peripheral surface of the cam ring and holds a movable plate in a state opposed to the other end face of the cam ring such that the movable plate can be moved along a central axis of the drive shaft. An inside of the shell and the movable plate defines a high-pressure chamber therein. Each adjacent pair of the vanes, the front head, and the movable plate defines a compression chamber therein.
